pub fn spherical_wave(
mode: Mode,
k: Complex,
position: [f64; 3],
helicity: bool,
radial: Radial,
) -> Result<VectorWave>Expand description
Evaluate a vector spherical wave in treams normalization.
Parity polarization 0 is M, 1 is N; helicity is (N + (2pol-1) M)/sqrt(2).
Upstream: treams.special.vsw_rA, vsw_A, vsw_rM, vsw_M, vsw_rN and vsw_N,
converted to Cartesian components as by treams.special.vsph2car.
